Availability Analysis of Heliotron J by the GO-FLOW methodology with AI Technologies

Heliotron J is a device to obtain fundamental knowledge for the realization of nuclear fusion. It is located at the Institute of Advanced Energy, Kyoto University. For the successful operation of the Heliotron J, availability of the water-cooling systems is essential matter. Reliability/availability analysis of the cooling systems have been performed by the GO-FLOW methodology for possible maintenance schedules and methods. The analysis has been conducted by using AI technologies. Higher harmonic diagnostic technology has been also used for evaluating the present status of electrical components. It is possible to determine the degree of deterioration. Analysis results could be utilized for the decision of the strategy of maintenance schedule and method. Further sophistication and improvements of analysis framework is planned by using AI technologies.
